The anti-twisting multifunctional low-attenuation butterfly-shaped optical cable can save laying resources. In large indoor buildings, such as shops, office buildings, hotels and the like, circular or square pipeline lines are arranged in the buildings, and the bayonet 13 can directly clamp products on the pipelines, so that the existing pipelines are utilized, and the laying resources are saved. In addition, after the bayonet 13 is clamped to a building pipe line, the product cannot twist in the construction and trial processes, and has certain torsion resistance.
In some embodiments, the bayonet 13 is rectangular, elastic buckles 14 are disposed on two sidewalls of the bayonet 13 adjacent to the connecting bridge 11, and the thickness of the elastic buckles 14 is gradually reduced in the direction that the opening of the bayonet 13 extends inwards, so that the opening forms a shape with a narrow outside and a wide inside. When the product buckle is fixed through the elastic buckle 14 after the pipe, the elastic buckle 14 forms an opening with a narrow outside and a wide inside, so that the optical cable can form interference fit with the laid pipeline, and the fixation is firmer and more reliable. In some embodiments, the resilient catch 14 has an arcuate shape that may facilitate stripping of the cable from the conduit when maintenance or replacement is required. The elastic buckle 14 can be made of rubber, TPU and other materials with very high elasticity, the product is attached to the pipe after the buckle 14 is arranged, and the product has excellent compression resistance and tensile resistance due to the reinforcing part of the outer circle. The size of the elastic buckle 14 can be designed according to the thickness of the pipe.
In some embodiments, the length of the connection bridge 11 is 1/4-3/4 times the maximum width B of the light unit mounting portion 12, and the width of the connection bridge 11 is 1/3-2/3 times the maximum width B of the light unit mounting portion 12. Thereby ensuring that the bridge 11 has sufficient space to accommodate the first strength members 51, the larger the diameter of the first strength members, the better the self-supporting capacity of the butterfly cable; and simultaneously, the space of the bayonet 13 is also ensured, so that the butterfly-shaped optical cable can more firmly clamp the attached pipe.
In some embodiments, if there is no pipe in the building that can be buckled, the pipe can be buckled at the buckling position through a clamp, so that construction wiring is performed.
In this embodiment, the butterfly-shaped optical unit 3 is an internal embedded butterfly-shaped optical cable, and after the sheath is stripped, the internal butterfly-shaped optical cable can be constructed independently; the sleeve light unit 2 can be a loose sleeve, a micro-beam tube or an optical fiber ribbon sleeve, different core numbers can be selected according to application scenes, the core number in each sleeve is different from 1-48, and optical fibers in the sleeve can be loose fibers, ribbon fibers, stacked flat ribbon fibers or coiled flexible ribbon fibers. The sleeve light unit 2 is selected, so that the product has wider application scenes, and can be freely applied in some special scenes. Therefore, the anti-twisting multifunctional low-attenuation butterfly-shaped optical cable can be suitable for various application scenes.
In this embodiment, the two ends of the outer sheath 1 are symmetrically provided with second reinforcing members 52, and the second reinforcing members 52 at the same end and the adjacent butterfly-shaped light units 3 or sleeve light units 2 form triangular distribution; the second reinforcing members 52 and the first reinforcing members 51 form triangular distribution, so that the strength and stability of the whole optical cable are improved. In the construction and operation process, the first reinforcing member 51 and the second reinforcing member 52 are formed into positioning members, and the first reinforcing member 51 can be clamped by a clamp for positioning, or the first reinforcing member 51 or the second reinforcing member 52 can be simultaneously fixed on a hardware for positioning, so that the optical cable is difficult to twist in the construction and operation process, the internal light unit is fully protected, and the phenomena such as cracking and the like are avoided. Meanwhile, in some embodiments, the first and second reinforcing members 51 and 52 are metal reinforcing members, glass fiber rods or aramid fiber reinforced plastic rods, so that the product has excellent rigidity.
In some embodiments, the second reinforcing member 52 is disposed at an inner vertex angle of the bayonet 13, thereby effectively preventing deformation or torsion at the bayonet 13.
In some embodiments, the outer jackets 1 at two ends of the connecting bridge 11 form a triangle or semicircle in cross section, and at the same time, the outer jackets 1 are in a flat structure as a whole, so that the space occupied by the optical cable after being laid is smaller. The outer sheath 1 is made of LSZH, TPU or PE materials.
In some embodiments, a third stiffener 53 is further provided within the outer sheath 1, the third stiffener 53 being provided along the periphery of the light unit mounting portion 12 and the connection bridge 11 of the outer sheath 1, away from the bayonet 13. The outer sheath includes a width B and a length L, and a direction extending along the width B is a width direction and a direction extending along the length L is a length direction. The outer periphery of the light unit mounting portion 12 and the connecting bridge 11 of the outer sheath 1 far from the bayonet 13 means that on the cross section of the optical cable, one side of the light unit mounting portion 12 and the connecting bridge 11 near to the outer surface of the sheath includes a periphery B1 in the width direction of the sheath and a periphery L1 in the length direction. The third reinforcement 53 is a flexible reinforcement, and the embedding of the outer ring flexible third reinforcement 53 can effectively enhance the tensile property of the product, and meanwhile, the surrounding embedding mode can effectively protect the internal light unit due to timely damage of the outer sheath.

In some embodiments, a fifth flattened reinforcement 55 is also provided in the inner wall of the sheath along one side of the bayonet 13. The fifth reinforcing member 55 is a flat fiberglass rod or a flat aramid plastic rod; the embedding of the side flat reinforcement, while effectively providing tensile properties, can also effectively prevent extrusion of the mounting fixture to the sides of the product from the sides, resulting in damage and failure of the internal light unit.
A tear 41 is provided on the light unit mounting portion 12, and the tear 41 is filled with a flexible filler 42. The tearing opening 41 is used as a peeling mode of the internal light unit, and the internal light unit can be peeled off for construction through the tearing opening 41; the tearing opening 41 adopts a filling mode, and the tearing opening 41 is covered by adopting a plurality of soft materials, or can be a sheath material (LSZH or TPU sheath material as much as possible) and can be spongy flexible materials, rubber or silica gel; the filled tearing port 41 can effectively avoid the situation that the tearing port 41 is cracked under the conditions that the sheath receives wind power, manual external force and the like.
The foregoing has outlined rather broadly the more detailed description of embodiments of the application, wherein the principles and embodiments of the application are explained in detail using specific examples, the above examples being provided solely to facilitate the understanding of the method and core concepts of the application; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present application, the present description should not be construed as limiting the present application in view of the above.
